best crypto exchange to buy btc

They have very professional customer support. they resolved a very tricky issue for me as fast as they could. Their communication is very fast and clear. They kept me up to date regularly. When the issue was resolved I've seen that they did exactly what they said they would. I am very happy with Coinbase, fees are a little high but the other cheaper crypto exchange platforms don't provide decent customer support. I am happy to have Coinbase as a primary crypto exchange.
